Noob askes question about water based ink

(1/3) > >>

BartJY:
I'm a total noob, and for that I apologize. I have a simple question, I hope it does not offend. Here it is:
If the ink has dried overnight on the shirt, how long and at what temperature do I need to flash dry it?

Thanks and sorry for wasting your time.

Bart

Bart, that was asked, and unfortunately only answered by me a week ago right here. http://www.theshirtboard.com/index.php/topic,24088.msg213994.html#msg213994

Hopefully, someone with a little experience curing waterbased ink with only a flash dryer will chime in, but I suspect that there is no real definite answer, as the dwell time to fully drive all of the water out of the ink could vary.
Is this the Speedball ink, or another? What do the instructions or tech sheet say?

Frog:
Ryonet's Screenprinting.com site has this article about using a flash dryer to cure inks.
https://www.screenprinting.com/pages/flash-dryer-faq. I've also seen references to using a hand iron like I told you I used on yardage.

Bottom line, whatever you try, make sure to do a wash test on a sample by laundering it a few times to check for full cure.

brandon:
Aquo makes a hybrid series that is low cure / air drying. Think of printing umbrellas, windbreakers and such. We do use Aquo as we like the ink but we have a gas dryer so we use their normal cure range of ink most of the time. But you could use this, do a quick flash I assume, and give the 24 to 48 hour cure time. However, I would test test test and document.

BartJY:
Frog,

Thank you for your patience. What I need are temperatures and duration for curing dry ink. For example: 250 degrees for 2 minutes. I'm aware that wet ink takes longer, but what about dry? No one seems to be able to provide me with that sort of information.

Once again thanks for your help.
Bart
